Laggy when come Ant Hill

[lephucthinh2000]

That's been 3days in game i don't go sleep and when i comeback to Red Ant Hill there's so lag ( on video ) because : 
- Red ant keep pilling food into their hill
We play Muiltiplay with 3 People, All platfrom is on Steam using Microsoft Account to play
My PC is : i5 13400F - 64GB RAM - 2060 VGA ( Enough to play with Epic settings ) but i choose medium quality with 60fps
This is real bug on grounded world, need some feedback.
